With the high luminosity upgrade to the LHC during LS4 the instantaneous luminosity at the LHCb experiment will be eventually increased by more than a factor of 6 to 10e34 cm2/s for Run 5.
As a part of Upgrade II the downstream tracker (Mighty-Tracker) is foreseen to be instrumented with 10m2 of HV-CMOS MAPS around the beam pipe. We will present the newest developments, what are the challenges for this detector and the plans for the Bonn contribution to this project for the next decade and beyond.
